Difficulty of early diagnosis of cerebral palsy Because the pediatric nervous system is in a stage of continuous development, the early movements of infants are controlled by subcortical centers and governed by reflexes, and most of the spontaneous movements are influenced by primitive reflexes, and although the brain tissue is damaged at this time, the symptoms are mostly not obvious. Therefore, except for those with obvious etiology and typical symptoms, early diagnosis is generally difficult. It is especially difficult to make early diagnosis within 3 months of birth. Careful diagnosis can only be made after careful examination by a specialized physician with professional training. In addition, most parents do not know enough about cerebral palsy, and even if symptoms appear early, they are often not noticed by parents. Some parents, influenced by certain traditional concepts, even if they find that their child is lagging behind in motor development compared to their peers at an early stage, they take it for granted that the child will reach normal after a period of time or when he/she grows up, and do not go to the hospital for checkups, and only go to the hospital after the child is 1 to 2 years old when the symptoms become obvious.
